How to populate an HTML table with JSON array values in Angular?

Question

I have an array as below:

var publicArray={
"settings": [{
"id": "1",
"deleted": "0",
"data": [{
"title": " Business Unit",
"value": "B1"
},
{
"title": "Comp ",
"value": "C1"
},
{
"title": " Pa Id",
"value": "P1"
}, {
"title": " NPI",
"value": "4535"
}
]
}, {
"id": "2",
"deleted": "0",
"data": [{
"title": " Business Unit",
"value": "B2"
},
{
"title": "Comp ",
"value": "C2"
},
{
"title": " Pa Id",
"value": "P2"
}, {
"title": " NPI",
"value": "34242"
}
]
}]
};

The array comes actually from a database, so it may extend, that means, that more rows will come as the array grows.

I need to populate an HTML table using this array as follow image.

I am new to this, please help me to do this.

Having component's property called publicArray you can you can achive that by writing the following template:

<table *ngIf="publicArray?.settings?.length && publicArray.settings[0].data?.length">
  <tr>
    <th>ID</th>
    <th *ngFor="let header of publicArray.settings[0].data">{{ header.title }}</th>
  </tr>
  <tr *ngFor="let row of publicArray.settings">
    <td>{{ row.id }}</td>
    <td *ngFor="let col of row.data">
      {{ col.value }}
    </td>
  </tr>
</table>

There are many libraries that you can use to create a table, like PrimeNG, Angular Material, etc.

I'll give you this example of "ngx smart table":
https://www.npmjs.com/package/ngx-smart-table.

You can follow the documentation:

By setting the settings{} object, you'll define your table header.
Then define another object from your brought data publicArray, so that it can match the same names as in the settings{}.
